2. Problem 2.24, p. 68, Note first that the current in the wire connecting the two portions is zero. Can you see why this must be so? Hint: make the entire right portion of the circuit (dependent source and 2 resistors) a super-node and write KCL for that super-node. The zero current in that wire means that the right portion of the circuit does not affect the left portion. However, the left portion does affect the right portion since 1, is in the left portion, and it is the dependency variable for the dependent source in the right portion. So, you can analyze the left portion of the circuit first, then use the result to analyze the right portion of the circuit.
17.2.24 For the circuit in Eig. 2.88, find V/V, in terms of a, R1,R2,R3, and R4. If R1 = = R2 = R3 = R4, what value of a will produce IV/V,1 = 10? 1. R1 WWW + Vs + R2 WWW alo R3 R4 ww Vo Figure 2.88 For Prob. 2.24.
